Project Name : Cricket World Cup
Introduction :
Our DBMS project is based on Cricket World Cup management. It provides
various information about the various teams participating in the World Cup, in
which all the major countries participate. It also provides us with information
about the various players participating in the tournament . The database
contains details of players, coaches and umpires among others. All the useful
information about the entire World Cup can be found here.
Data Requirements:
Entities:
1) Team is an entity type which has many attributes like Team Name
which uses the data type varchar. Every team has been given a Team
ID which is the primary key which is of data type varchar. Team
Ranking, Number of Batsmen and Number of Bowlers are of the data
type number. There is another attribute - Wicketkeeper which is of
multivalued type and accepts varchar data type. Primary key cannot
have null value.
2) Players is an entity type which has an attribute – Player Name which
is of the data type varchar. It has a primary key, Player ID, which
cannot have null value. It has a foreign key, Team ID which is the
primary key of the entity, Team. There is a complex attribute,
Number of matches played, which comprises of Number of Test
Matches, Number of T20 Matches, Number of World Cup Matches
and Number of ODIs.
3) Batsman is an entity type which has the attributes – Number of sixes
hit, Number of Fours hit, the batting average, and the total runs
scored. All of these attributes are of the data type number.
4) Bowler is an entity type which has the attribute – type of batsman
with varchar data type. It also includes number of wickets and
economy which are of the data type number.
5) Umpire is an entity type which has the attributes name and country
of origin of data type varchar. The primary key of this is Umpire Id
which is of varchar data type. It also has an attribute Number of
matches of data type number.
6) Coach is an entity type with a foreign key, Team ID, which is a
primary key of entity type, Team. It has a primary key, Coach ID, of
data type varchar. It also has another attribute of data type varchar,
Name.
7) Captain is an entity type with a primary key, Captain ID of data type
varchar. It has two foreign keys, i) Player id from table Players and ii)
Team ID from table Team. Number of years of captaincy and Number
of wins are also attributes of this table of data type number.
8) Matches is an entity type with a primary key, match ID, of varchar
data type. It has attributes like Team1 Name, Team2 Name, Stadium,
Winner Team and Loser Team of data type varchar. Match date is an
attribute which uses the datatype date. Match time is an attribute
which is of the data type time.
Relationships:
Cricket player plays in team (N-1)
A cricket player can play in only one team but a team can have many players in
it but a team must have players in it. So, the relationship becomes (N-1).
Coach manages team(1-N)
Coach can manage a single team, but each team can have many coaches (like
batting coach, fielding coach, bowling coach). But it is compulsory for a team to
have a coach. So, the relationship is 1-N
Team plays match(M-N)
Team can play many matches and a match can be played by two teams. So, the
relationship is M-N.
Matches are umpired by Umpire(M-N)
An umpire can umpire in many matches and a match can have two umpires.
So, the relationship is M-N.
Team headed by a Captain (1-1)
A team has 1 captain and a captain is from single team only. So the relationship
is 1-1.
Functional Requirements:
1) VIEWER
System must allow users to login if they enter the correct login id and
password. The users must be able to see the player details of each player in
the database. Scores of each match must be visible. Match date and venue
should be displayed on the login if the users seek for it.
System should display the complete roster of a team including the captain and
the players playing in the top 11 and the current rank of the team. The details
of the coach must also be available to the users. Referees and their details are
also important as the players and the viewers want to see the best referees
managing their team’s match. Each player’s statistics should also be available
like total runs , number of matches played etc.
System should display data on each match which has been scored in the
duration of the entire tournament. System should allow fixtures to be searched
and the date should also be available.

2) ADMINISTRATOR
Administrator is in charge of creating the website which is used to access the
database. Administrator has all the privileges of the user but has the authority
to add and remove data from the database which the user cannot do.
Administrator is responsible for creating different user accounts and assigning
the id and password. Administrators are the one who generate the fixtures and
update them in the database. They should be allowed to enter the team name
of home and away teams. He should have the authority to enter and modify
the match details like time and venue in case the need to be changed.
If any player has been punished for bad behaviour or other reasons and
cannot play in the World Cup anymore the administrator should be able to
delete the data from the database. The rank of every team must keep being
modified after each match. After a team is eliminated or disqualified the
administrator should be able to delete the entire team’s record.
